- To create a survivorship curve for the Andean condor: Graph Title: Survivorship Curve for Andean Condor Y-axis: Labeled "Survivorship" with indicators for "Low," "Medium," and "High" levels, ranging from 0 to 100% of the total initial cohort size. X-axis: Labeled "Life Span" with stages "Young" (0-5 years), "Middle-aged" (6-37 years), and "Old" (38-75 years). Key Features of the Curve: Begins high, reflecting near-total survival from birth to maturity due to low mortality and protected upbringing. remains flat and high through the middle age, indicating sustained low mortality. shows a steep decline in old age, representing increased mortality as individuals reach the latter part of their lifespan.Explain the difference and give an example of Type 1, 2, and 3 Survivorship curvesWhich of the following charts correctly plots the survivorship curve of the Song Thrush?

- Describe the three different survivorship curves and give suitable examples of each.For each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. Andean condors reproduce slowly. Females lay one or two eggs every other year. The offspring that hatch are well-protected and cared for, and many reach sexual maturity at five to six years. Although their numbers are being threatened by human impacts, they are naturally long-lived, surviving for seventy to seventy-five years.Plot by hand the survivorship data for the Gray Squirrel life table. A survivorship curve has age or age class (x) on the x-axis and lx on the y-axis.

- Calculate standardised survival (lx), % mortality, and age-specific survival (px) and mortality (qx) rates for Ovis dalli and Quercus robur by filling in Table 1For each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Even before they hatch, the offspring are prone to high rates of predation. Many offspring die before they reach adulthood. Of the offspring that do survive, some will die in adulthood, and some will live their entire natural life span.https://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html This section starts explaining how scientists use the population survey data that are collected to model how the lionfish population changes over time. These models enable scientists to make predictions about population changes, which is an important element of developing plans for managing the lionfish population You'll be using the discrete-time logistic model that is described on this page in future parts of the case study, so make sure to carefully read through the explanation of this mathematical model. Even if you don't have a strong math background, this case study walks through the equation step by step. 6)Which of the following are constant terms in the discrete-time logistic model? choose all that apply a)Nt b)ΔN c)t d)K e)Δt f)rmax,d g)None of these
